K. EMDE FASTENING MEANS April 2, 1946.

Filed Dec. 31, 1943 r J l l HIS ATTORNEY 7 Prestressed coil spring 30wound around pivot v 1 pin 25 has one of its ends 3| engaging levermember l9 and the other one of its ends 32 engaging member It so thatthe end 2| of lever member 1 H! is normally pressed into engagement withmember It or presses in a clamping manner the wearers clothing againstthe wall l5 upon which the fastening device I is mounted.

Whenmounted on the wall or apertured support or closure member It, thepivoted'lever member or wearing apparel engaging member apparel or othersupporting means which is inserted between spring biased pivoted leverl9 and V the wall or closure member l5.

Springbiased end ill of lever 19 is displaced from normal engagementwith wall l by press- I9 is normally in the position shown in Fig. 51;;I wherein end 2! is pressed against any wearing be obvious to thoseskilled in the art that changes and modifications may be made withoutdeparting from this invention in its broader aspects,

and therefore the aim in the appended claims is to cover all suchchanges and modifications as fall within the true spirit and scope ofthis invention.

I claim: 7 r I i. In a clasp supporting arrangement a member havingintegrally formed thereon a pair of oppositely extending projections,one of said projections being resilient and extending from a pointintermediate the ends of said member on one side thereof at an acuteangle therewith in the direction of. one end of said member, the otherprojection extending from said one side at theother end of said memberand being L-shaped, with the vertical portion of the L extendingsubstaning end 22 to the right in Fig. 4, in which case member l9 pivotsaround pivot pin 26 against the V action of prestressed coil spring 38and ultimately assumes the position shown in Fig. 5 where end' 22engages the supporting member i5.

One of the particular features of the present i invention is the easewith which the fastening device or cliplt may be removed from thehearing aid or other device to which it is attached. For example, in thehearing aid apparatus shown in Figs i l and 2, the clip Iii may beremoved from the front as shown in Fig. 1, wherein it is eiTective tosecure the hearing aid apparatus within the users pocket withoutinterfering with sound transmitted to'a microphone located behind paneland be fastened to the back of the same hearing aid apparatus providedwith the same type of apertures l3, l4 and 27, 28 respectively on thefront and back sides of such hearing aid apparatus.

The clip or fastening device, shown in Fig. 7

;' detached from the structure it is arranged to support, is readily andeasily mounted on the wall f or closure member l5 by (1) insertingprojection I2 into opening l4, 2) pressing the composite clip in thedownward'direction in Fig. 4 until the projection is in position to beinserted Q through'opening l3, (3) passing projection ll throughopeningl3, and (4) then releasing the composite clip id in whichcase theupstanding portion of projection H is pressed upward due to theresilient nature of projection 12 to assume the position shown in Fig.4.

The fastening device or clip in is easily detached from Wall iii in Fig.4 by (1) moving the device l6 downward relative to wall" I5, in whichcase projection i2 is deformed within its resilient limits to a'pointwhere projection'll may be passed through opening [3 and then by (2)pivj o'ting the entire clip I0 at the contact point between projectionl2 and wall l5 so as to pass projection ll through opening l3 and then(3) sliding projection l2 out of opening l4. 7 1 7 'It is noted thatopening I3 is slightly larger 7 than the upstanding portion ofprojection II in Fig. '4 so as to allow passage of projection Htherethrough. Opening l lis defined by a curved upper wall lllforguiding projection 12 in the process of mounting clip ill on wall t5 andby a portion 4! of reduced wall thickness for engagement betweenresilient projection l2 and wall I5.

It is noted further that the openings l3, M on the one hand and openings21 and 28 on the other hand are spacedvapart a distance slightly lessthan the distance between the ends of projections II and I2.

While particular embodiments of the present 1 invention have been shownand described, it will shaped.

tially perpendicular to the plane ofsaid thin sheet member and thehorizontal portion of the L extending substantially parallel to theplane of said sheet member inadirection opposite to the direction inwhich .said resilient projection extends. v 2. In a clasp supportingarrangement a thin sheet member having integrally formed thereon a pairof oppositely extending projections, one of said projections beingresilient and extending from a point intermediatethe ends of said memberon one side'thereof at an'acuteangle therewith in the direction of, oneend'of said member, the other projection extending from saidone side atthe other end of said member and being hook shaped, said one projectionbeing integrally formed withsaid sheet memberandforming therewith aresilient clamp whereby said sheet member may be clamped resiliently andreleasably to a supporting wallor the like.

4. The combination of a clasp supporting member with an aperturedsupport havin an inner and an outer wall surface, said clasp supporting1 member being of thin sheet material andhaving integrally formedthereon a pair of oppositely extending projections, one ofsaidprojections being resilient and extending from a point intermediatethe ends. of said member on one side thereof at an acute angle therewithin the direction of one end of said member, the other projectionextending from said one side at the Other end of saidmember and being L-shaped with the vertical portion of the L extending substantiallyperpendicular to the plane of said. thin sheet member and the horizontalportion of the Lextending substantially. parallel to the plane of saidsheet member in a direction opposite to thedirection in-which saidresilient projection extends, said support having a pair of aperturesspaced a distance slightly less than the distance betweentheends of saidprojections, oneof said apertures having its opening area and shapeslightly greater than the projected area and shape of said horizontalportion ofsaidL and the other one ofsaid-apertures having its openingarea and shape slightly greater than the projected ,area ofsaidresilient projection, said'acutqangle and the wall thickness of saidapertured support and the other one of said apertures having its beingso dimensioned that insertion of said resilient projection through itscorresponding opening from the outer wall of said support to engagementwith the inner wall of said support results in stressing of saidresilient projection, whereby said clasp supporting member may beattached to said apertured support by initially inserting the free endof said resilient projection from the outer side of said support intoits corresponding opening into sliding resilient engagement with theinner wall surface of said support thereby stressing said resilientprojection until said L-shaped projection comes in registry with itsopening, then inserting said L-shaped projection through itscorresponding opening and then moving said horizontal portion of the Linto sliding engagement with said inner wall surface wherein it is heldin spring biased condition due to the stressed condition of saidresilient projection.

5. The combination of a clasp supporting member with an aperturedsupport having an outer and an inner wall surface, said clasp supportingmember having formed thereon a pair of projections, one of saidprojections being resilient and extending from one side of said memberat an acute angle therewith in the direction of one end of said memberto form a resilient clamping memher, the other projection extending fromsaid one side near the other end of said member and being hook-shaped,said support having a pair of apertures spaced a distance slightly lessthan the distance between the ends of said projections, one of saidapertures having its opening area and shape slightly greater than theprojected area and shape of said hook-shaped projection opening area andshape slightly greater than the projected area of said resilientprojection, said acute angle and the wall thickness of said aperturedsupport being so dimensioned that insertion oi said resilient projectionthrough its corresponding opening from the outer Wall of said sup.- portto engagement with the inner wall surface of said support results instressing of said resilient projection, whereby said clasp supportingmember may be attached to said apertured support by initially insertingthe free end of said resilient projection from the outer side of saidsupport into its corresponding opening into sliding resilient engagementwith the inner wall surface 01 said support thereby stressing saidresilient projection until said l1ook-shaped projection comes intoregistry with its opening, then inserting said hook-shaped projectionthrough its corresponding aperture and then moving said hook-shapedprojection into sliding engagement with said inner wall surface whereinit is held in spring biased condition due to the stressed condition ofsaid resilient projection.
